For overview information about drive LEDs and how they work, see “Front-Panel
LEDs” on page 5-2.
Note –
Whenever media scan is running on a drive, its front-panel LED flashes green.
It is normal for almost all front-panel drive LEDs to flash green unless media scanning
is terminated. For more information, refer to the
SANnet II Family RAID Firmware
User’s Guide .
Caution –
When you rotate or replace drives, make sure that all I/O is stopped. To
prevent any possible data loss, back up user data to another storage device prior to
replacing a disk drive.
